Hey!

My weight/height percentage is in the 33rd percentile. what does this mean??

thx.

if you are in the 33rd percentile for both height and weight, you are taller and weigh more than 33% of all adult females (assuming you are an adult yourself. if you are not, the classification would likely be made within an age group).

is that good? weighing more than 33%? does that mean i weigh less than 67% of ppl in my age group and my height is lower than 67% aw well???

I would not go by that. You'd be far better served by going by your bodyfat percentage. It's a much better indicator of progress than any measure of bodyweight. If you can't go by bodyfat percentage then you'd be go by measurements instead of weight.
